Constraint Fixture

Constraint Fixture executes a method for each row using the row cell values as input. The method name is created by concatenating the header row values. Each row is marked according to the boolean return value of the method.

By default, rows returning true are marked green.

when test is⇓

sample constraint
greater	than
1	2
2	1

then result is

sample constraint
greater	than
1	2
2	1

We can specify that rows returning false are marked green.

when test is⇓

sample constraints

make fixture	false
greater	than
1	2
2	1

then result is

sample constraints

make fixture	false
greater	than
1	2
2	1

A repeat string can be set to copy previous row values.

when test is⇓

sample constraints

make fixture repeat	ditto
greater	than
1	2
ditto	3
2	1

then result is

'SetUp' and 'TearDown' methods are executed if they exist.

when test is⇓

sample constraint
greater	than
1	2
2	1

then result is

sample constraint
greater	than
1	2
2	1

with log

SetUp() GreaterThan(1,2) GreaterThan(2,1) TearDown()

Errors are reported.

when test is⇓

then result is
